Failure to activate credit card after it was stopped by the bank without warning

My additional credit card was stopped by the bank after I received one sms informing me to submit a copy of my wifes ID who uses the card. The sms looked very ***** and I ignored it because I thought it was a ****. I never received any further communication from the bank after the sms. About a month later they just cancelled the card without any warning. I phoned fnb and submitted all the proof they needed the same day. A lady from fnb phoned me back and said she will follow up and make sure the problem gets resolved as soon as possible. It is now four working days later and after numerous emails and complaints to fnb without any response form them the credit card is still not reactivated. Being a client for over 7 years without missing one payment on my credit cards, home loans or car loans, do you really think the way you handle me is fair? Is it really so difficult to just phone me back and tell me what is going on and to activate a credit card? You reading this message, will you like it if your personnel cards got stopped by the bank without any valid reason leaving you unable to pay for stuff on a daily basis?
